The purpose of a base coat in nail polish application is primarily to protect the nail and enhance color adherence. When applied before the colored polish, the base coat creates a smooth surface that helps the color stay on better and last longer. This layer acts as a barrier against any staining that colored polishes might cause, particularly with darker shades or those containing pigments that can discolor the nail surface.

In addition, the consistency and formulation of the base coat help it to meld more effectively with the nail, allowing for better adhesion of subsequent layers of polish. This not only leads to a more vibrant and even application of color but can also contribute to a longer wear time for the polish.

While enhancing shine and strengthening the nail are beneficial properties, they do not directly address the primary function of protecting the nail and ensuring the polish adheres well. Reducing drying time is a consideration, but it’s more typically associated with top coats rather than base coats. Therefore, the option focusing on protection and adherence is the most accurate representation of the base coat's purpose.
